The chipset drivers aren't really drivers, they're mostly just installation hints for the Microsoft drivers (if required) work properly unknown device doesn't show in device manager. Bascially, if all your devices have been installed correctly, the Intel Chipset driver won't do anything at all! If it does update something, you've most likely got either recent hardware, such as Sandy Bridge stuff, or something hadn't installed properly before :S The Rapid Storage driver is a proper performance driver, and installing the later version may provide benefits through better driver optimisations etc, so that one is definitely worth getting! That said, I take back the 'definite' statement if you install it and something blows up... lol
does anyone making a custom driver for the 2915abg? I was able to install the latest software for it to use like for a week and now it stop working saying no adapter found. maybe just a modded inf will do?
